Why This Fails Locally
Most of the housing stock across this service area went up between 1969 and 2014
With the bulk of it dating to the 1980s and 90s across the 18 communities we cover. That matters for cables because a house built in that window is old enough that its original lift cables are at or past the end of their service life, but the owner usually hasn't thought about them once since the door was installed. The galvanized coating on a factory cable is rated for a certain number of open-close cycles, and a door that age has usually logged tens of thousands of them.

The climate band here is mild with occasional freeze events
Not the deep-freeze cycling that snaps cables through thermal contraction up north. What gets cables here instead is humidity and salt air drifting in off the Gulf side of the region. That combination corrodes the strands from the inside of the cable, under the galvanizing, long before the outer coating looks bad. A cable can look fine on a Tuesday and let go on a Thursday because the corrosion is happening where you can't see it, at the drum and at the bottom bracket.
Houses built later in that 1969-2014 range, closer to 2014, sometimes have better coated cable from the factory
But a lot of this area's stock sits in the 1980s-90s pocket where the original hardware is simply due.
Where This Job Goes Sideways
A frayed cable rarely fails cleanly. What usually happens is one strand goes first, the cable keeps running under load with less capacity than it had, and the door starts to rack slightly to one side as it travels. Owners notice the door
